+# Currency Exchange Rates
+
+Currency exchange rates are fetched from the following API endpoint:
+
+```
+https://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml
+```
+
+This endpoint does not require any authentication, thus no configuration is required in order to enable the currency conversion feature in the unit converter.

+# External APIs
+
+Kvæsitso integrates with a number of external APIs. Most of them require some sort of authentication, like an API key. These API keys are not part of the GitHub repository. If you want to build Kvæsitso from source with all features enabled, follow the steps in this chapter.
+
+:::info
+Kvæsitso is still buildable even without these steps, but some features will be disabled in the resulting APK. If all you need is a debug build for testing purposes, you can probably skip this chapter.

+# Weather Services
+
+1. Copy the `weather/src/main/res/values/config_example.xml` to `weather/src/main/res/values/config.xml`
+
+#### OpenWeatherMap
+
+OpenWeatherMap offers 1 000 000 free API calls per month. However forecasts are only available for
+the next 5 days and only every 3 hours. Also note that each weather update uses two API calls (
+current weather + forecast).
+
+1. Register at [OpenWeatherMap](https://openweathermap.org/)
+1. Navigate to your user profile > API keys
+1. Create a new API key
+1. Uncomment the resource `openweather_key` in config.xml and paste your key as value.
+
+#### HERE
+
+HERE offers 250 000 free API calls per month. Each weather update uses one call.
+
+1. Sign up at the [HERE developer portal](https://developer.here.com/)
+1. Create a new project.
+1. Go to project details and under JavaScript, create a new API key.
+1. Uncomment the resource `here_key` in config.xml and paste your key as value.
+
+#### Meteorologisk institutt[^1]
+
+The Norwegian Meteorological Institute offers a free weather API. It has a rate limit of 20
+requests/s. You do not need an API key, however they require an
+identification and contact data to be present in the User Agent header in each request. Read the exact rules in their
+[Terms of Service](https://api.met.no/doc/TermsOfService).
+
+1. Uncomment `metno_contact` in config.xml. Fill in your contact data (an email address or a website
+   where your contact data can be found). This will be sent in the User Agent header, which will be
+   composed like
+   this:
+   ```
+    User-Agent: "{app package name}/signature:{app siganture hash} {@string/metno_contact}"
+   ```
+
+#### Bright Sky / Deutscher Wetterdienst[^1]
+
+Bright Sky is an API that converts data published by the Deutscher Wetterdienst to an easier
+to work with JSON format. The API is free to use and requires no additional configuration, however
+it only provides weather data for locations in Germany.
+
+[^1]:
+    These weather providers do not provide any means of geocoding or location lookup. Instead, the
+    Android Geocoder API is used to lookup locations (in fixed location mode) and location names (in
+    auto location mode). While most devices ship a Geocoder as part of the Google Play service, some
+    might not have a Geocoder installed. In these cases, this provider might not work properly (no
+    support for fixed locations and lat/lon values will be displayed instead of location names).

+# Wikipedia
+
+Kvæsitso uses the [Mediawiki API](https://www.mediawiki.org/wiki/API:Main_page) to load data from Wikipedia. No further configuration is required. The default Mediawiki installation URL is language-dependend and can be configured with `wikipedia_url` string resource in the `:i18n` module.
